Check Engine Light Diagnostic and Repair by BN Auto Mechanic

Introduction

The check engine light is a crucial warning system in modern vehicles, indicating potential issues with the engine, transmission, or emissions system. Ignoring this warning can lead to costly repairs or even vehicle failure.

Common Causes of a Check Engine Light

Several factors can trigger the check engine light, including:
